The invention relates to baling presses and refers more particularly to baling presses of A One of that type having open upper ends. the objects of the invention is to so construct the baling press that but relatively small clearance above the baling press is requlred for moving the platen transversely beyond the open end of the baling press. Another object is to so arrange the parts of the baling press that the platen is movable transversely beyond the open end of the baling press 1n a direction away from the flexible driving" connection to avoidinterferencewith the latter. A further object is to so form the Figure 1 is an end elevation of a bailing press embodying my invention;

Figure 2 is a side elevation partly in section; I

Figure 3 is a transverse section through the sprocket.

The bailing presshas the vertically ex tending bailing chamber 1 within the lower end of which is located the lower stationary platen 2. 3 is the upper platen which 1s mov able longitudinally within the ballng cham ber.

provided the flexible driving connections 4 at the opposite ends of the baling chamber, a each extending around an idler wheel 5 at the upper end of the baling press and a drlvingwheel 6 at the lower end thereof, the two driving wheels being mounted upon the drive shaft 7, which is rotated by means of suitableworm gearing within thehousingS, the worm of which is connected to the electric motor 9.

The idler wheel and driving wheel for each flexible driving connection is so located that the flexible driving connection is at one side of the longitudinal median plane of the baling chamber. 10 are links connected at one parts as more fully hereinafter set For actuating the upper platen we have.

end to the upper platenand at the other end to the flexible driving connections 4 by means of the arms 11. The connection of each link to the upper platen is made through the beam 12 of this platen and is such that each link extends at right angles to the platen. Specifically each link is connected to the beam by a pivot extending transversely of the beam. "T he connection between each link and its arm '11 is pivotal so that the link may move angu' 'larlyjor swin or relative to its arm.

13 are tracks at the-opposite ends of the ba ling press, each having the vertically extending portion 14 and the transversely extending portion 14, the first portion extend 'ing longitudinally centrally at the end of the {ba ling chamber and the second portion extending transversely thereof beyond its open upper end and in a direction away from the flexible driving connection at that end. 15

and 16 are shoes upon each of the links 10 for engaging the track at the corresponding end of the baling press. These shoes are in the nature of rollers and the shoe 15 is secured to the link near its point of connection to" the upper platen, while the shoe 16 is secured to thelink at its point of connection to its "arm; The arrangement is such that the shoes 15 are engageable with both portions of'the tracks while the shoes '16 are engage-"- --able only with the vertically extending portions thereof, and as a consequence, operation of the flexible driving connections to raise the upper platen from its compressing position within the-'baling chamber carries the upper platen upwardly and beyond the open upper end of the baling chamber and then transversely-andaway from the flexible driving connections, during which time the links and the upper platen are angularly moved or tilted so that the upper platen finally assumes a position extending longitudinally of the baling chamber and beyond a side thereof to clear its open upper end.

' Each flexible driving connection is preferablymade up of the sprocket chainl? and the flexible cable 18, the former being connected to the end of the link 10 at that end of the baling press and in such a manner that it operates to efiect a direct pull upon the linkduring the compressing movement of the upper platen. This sprocket chain extends around its respective driving wheel 6, which is in the nature of a sprocket wheel. The flexible cable 18 has one end directly connected to the free end of the arm 11 at that end of the baling press, the opposite end of this flexible cable being directly connected to the sprocket chain above its driving sprocket. To provide for using smaller diametered driving sprockets and still obtain the required compressing pressure, the sprocket chain is provided with rollers 19 located between its links and surrounding the link pivots, these rollers having a rolling engagement with the teeth.
